cmake: add OpenBSD support (no librt) (#21)

Use nixbuild/nix-quick-install-action which pairs well with
nix-community/cache-nix-action.

Should help with build times by reducing the number of packages needing
to be re-downloaded on each run.

Parameters are taken from https://github.com/nix-community/cache-nix-action
and may be tweaked later.

 # hyprwayland-scanner
 A Hyprland implementation of wayland-scanner, in and for C++.
 
+hw-s automatically generates properly RAII-ready, modern C++ bindings for Wayland protocols, for
+either servers or clients.
+
 ## Usage
 
 ```sh
 hyprwayland-scanner '/path/to/proto' '/path/to/output/directory'
 ```
 
+### Options
+
+- `--client` -> generate client code
+- `--wayland-enums` -> use wayland enum naming (snake instead of camel)
+
 ## Dependencies
 
 Requires a compiler with C++23 support.
